  • a sealing strip which emerges from the axial flange surface, is used to seal the oil pan that can be screwed against the crankshaft housing from below.
  • Two nuts are welded into the housing cover so that when the oil pan is screwed on, the sealing strip between the housing cover and the oil pan can be compressed with sufficient surface pressure in order to create a seal.
  • the invention has for its object to improve a generic seal so that on the one hand the processing costs for the counter surfaces can be significantly reduced or machining can even be completely omitted and on the other hand the sealing effect is further improved and also guaranteed in the long term.

  • Wax, sealing lacquer or the like can preferably be used.
  • the housing and flange surfaces filled and sealed elastically by the elastomeric material of the sealing strips, but also the micro-roughness, step transitions, pores and the like are filled and sealed by the plastically deformable sealant.
  • the invention which will be described in more detail below with the aid of exemplary embodiments, therefore achieves a substantial improvement in the sealing effect on the one hand, while on the other hand precise machining of the flange surfaces can be dispensed with, as a result of which the manufacturing and processing costs can be significantly reduced.

Abstract

L'invention concerne une garniture d'étanchéité statique pour moteurs à combustion interne, notamment couvercle de fermeture pour carter de vilebrequin ou de boîte, qui comprend un corps de base en métal ou similaire, muni de trous pour recevoir des vis de fixation, ainsi que des bandes d'étanchéité en matériau élastomère, fixées par vulcanisation ou procédé similaire sur ledit corps de base. Les bandes d'étanchéité comportent au moins une nervure faisant saillie dans le sens axial. Afin d'une part de réduire sensiblement les frais d'usinage des contre-surfaces et d'autre part de rendre l'étanchéification encore plus efficace, les bandes d'étanchéité (5) comportent sur la face (10) opposée à la face de bride (9) du carter (8), des cavités (11, 16, 17) dans lesquelles est introduit un agent d'étanchéité.
